The Dallas Fallen Officer Foundation was established in 2009 by active Dallas Police Officers. The foundation was designed to assist the immediate families of "fallen officers" injured or killed in the line-of-duty, who are diagnosed with catastrophic illnesses, or experience other catastrophic events.

The Dallas Fallen Officer Foundation is a tax-deductable, nonprofit organization established under provisions of the Internal Revenue Service and the Office of the Texas Secretary of State to operate in the State of Texas.
